VAPORIZING DEVICE FOR LUBRICANTS.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed December 11, 1906. Serial No 347,338.

To all whom it may concern:

Be it known that I, WILLIAM P. MAIN- GAULT, a citizen of the UnitedStates, residing at Memphis, in the county of Shelby and State ofTennessee, have invented new and useful Improvements in VaporizingDevices for Lubricants, of which the following is a specification.

This invention relates to a vaporizing de vice for lubricants of thatclass wherein. the lubricant is fed to a receptacle connected to asteam-supply pipe at'opposite extremities, the one connection betweenthe receptacle and steam-supply pipe being the outlet into the latter ofa vaporized lubricant and steam, the object of such apparatus being toreduce the lubricant to vapor or spray form and commingle it with steamfor effective application to the working parts of machinery designed tobe operated by steamprssure such, for example, as the cylinder of anenglue.

The present vaporizing device is simplified in its construction andoperates to effectively vaporize the lubricant under steam heat and toinsure a regular feed of the vaporized lubricant with the steam into thetubular conveying means or pipe connected to the machineryadapted to belubricated.

, The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter specified.

In the drawings, Figure 1 is a side elevation of a vaporizing deviceembodying the features of the invention. Fig. 2 is a vertical sectionalview of the same. Fig. 3 is a detail elevation of the vaporizing cone orhell forming the essential feature of the invention.

The numeral 1 designates a receptacle or receiver which may be of anysuitable construction and preferably consists of a body or retort havinga screw-cap 2, provided with a laterally-directed oil-feed-pipeconnection 3,

to which a suitable pipe, (not shown,) may be attached and supply thevaporizing device with lubricant or oil from a suitable source. Risingfrom the cap 2 is a steam-supply pipe 4, which is connected to a pipe 5,running from a steam-conduit 6, the latter serving as the steam-supplymeans for machinery designed to be operated by steam-pressure such, forexample, as a steam-cylinder or steam-chest or any analogoussteam-controlled element. The bottom 7 of the receptacle or receiver 1is horizontally fiat and closed, and projecting outwardly therefrom is acoupling flange or nipple 8 to receive a suitable attaching connectionwhich engages the steam-conduit 6.

Arranged in the receptacle or receiver 1 is a cone or bell 10,comprising a cylindrical body with a conical top, and from the apex ofthe top downwardly over the said body a spiral groove 11 extends and atthe lower end of the body communicates with or is disposed'over acircumferential gutter 12, which is formed by diametrically reducing thelower part of the body, as at 13, and providing a lower upstandingguard-flange 14. The cone or bell 10 is hollow, and the body thereof isimperfo'rate. The bottom, as at 15, is fully open and is held above thebottom 7 of the receptacle or receiver to permit the steam entering thereceiver to circulate within the cone or bell with material advantage inheating the latter and reducing the lubricant flowing downwardlythereover. A small feed-pipe 16 connects with the flange of the gutter12 and passes out through the nipple 8 into the conduit 6 and terminatesin a downwardly-deflected nozzle or outlet extremity 17. I

The operation of the improved device is as follows: The steam-conduit 6conducts the steam from the generator to the machinery to be actuated,and said conduit may, for instance, lead from the dome of a steam-boilerto a valve-chest or chests or in some instances to the cylinder orcylinders of a steam-engine. A portion of the live steam conveyedthrough the conduit 6 passes by means of the pipes 5 and 4 into thereceptacleor receiver 1, it being observed that the steam passes acrossthe entrance-opening or the point where the lubricant passes into thecap 2 and acts to force the lubricant downwardly to the apex of theconical top of the cone or bell 10, the opening in the cap 2, as at 18,directly over the apex of the conical cap of the cone or bell being ofsuch reduced diameter as to cause the steam and 'oil to strikethereagainst. The lubricant or oil and steam both strike the apex of thecap, and the contact of the steam with the oil heats and reduces thelatter, the steam passing down, around, and up into the cone or bell,and finally escaping through the nipple 8 back into the conduit 6-.wardly over the cone or bell through the spiral groove 11 and graduallybecomes thin.

ner in its course downwardly toward the lower end of the cone or bell byreason of the The oil flows down IIC heat, and when the oil or lubricantreaches the gutter 12 it is in very thin condition. From thev gutter thereduced oil or lubricant passes out through the small pipe 16 and iscommingled with the steam and vaporized or sprayed in the conduit 12 andin such condition passes to the machinery adapted to be lubricated. Itwill be understood that the extent of vaporization of the lubricant oroil depends in a large degree upon the character of the lubricantemployed and also upon the intensity of the heat.

The downwardly directed or curved nozzle 17 of the pipe 16 partakessomewhat of the nature of an injector to deliver the re duced lubricantabout centrally with relation to the interior of the conduit 6, so thatthe live steam passing through the said conduit will spray the reducedlubricant, and an intimate admixture of the oil or vapors or particleswith the live steam in the conduit will take place with obviousadvantages in lubricating machinery.

It is proposed to use the improved vaporizing device with any kind ofmachinery, and as the steam which is directed, as it were, by means of aby-pass from the main supplyconduit 6 through the vaporizing device iscaused to again return to the main conduit there is practically no lossof steam, but, on

the contrary,-a simplified and effective means for commingling thelubricant with the steam and economically utilizing a lubricant.

Another advantage of the improved vaporizing device is that the supplyof reduced lubricant through the pipe 16 is continuous or uninterruptedin view of the provision of the gutter 12, and the latter being underthe effect of steam heat the lubricant will be maintained in a desiredthin condition for reduction to spray by its passage through the pipe 16into the main conduit 6.

Having thus fully described the invention, what is claimed is" 1. Thecombination with a steamsupply conduit, of a receiver connected at itsupper extremity to said conduit, an oil-supply means at the upperportion of the receiver, a connection at the lower portion of thereceiver with the conduit, a cone or bell within the receiver having agutter at its lower extremity, the body of the cone or hell beingspirally grooved from the top to the bottom thereof, and a reduced pipeattached to the gutter and also projecting into the conduit.

2. A lubricant-vaporizing device of the class specified, comprising areceiver having a steam and lubricant feed connection at the upperportion thereof, and an outlet connection at the lower extremity of thesame, a hollow cone or bell within the receiver having a grooveextending spirally thereover from the top to the bottom and alsoprovided with a gutter at its lower extremity, and an outlet-pipeconnected to the said gutter.

3. A lubricant-vaporizing device of the class specified, comprising areceiverhaving a steam and oil connection at-theupper portion thereof,acone orbell disposed in the receiver and having the apex projecting upin a position to first receive the lubricant and steam fed to thereceiver, the lower extremity of the cone or bell havingacircumferential gutter, and an outlet-pipe attached to the said gutter.

4. The combination with a steam-supply conduit, of a receiver having-acap with an opening therethrough and provided with steam-supply andlubricant connections above the opening, the lower extremity of thereceiver having an outlet connection, a cone or bell disposed in thereceiver and having the apex thereof projecting'upwardly into theopening to first receive the steam and lubricant, the body'of the coneor bell being imperforate and open at the bottom and having a grooveextending spirally downward thereover from the apex to the bottom of thesame, and an outlet-'pipecon ibieptedto the lower extremity of'the coneor e l.

5. The combination with a steam supply conduit, of a receiver havingtheupperportion thereof 'connectedto said conduit, and also providedwith an upper lubricant-supply connectioh and a lower outlet, a'tubularcone or bell disposed in the receiver and having an open bottom and theremaining portion of the body thereof imperforate, the body of the coneor bell also having a groove spirally extending downwardly thereoverfrom the apex to the-bottom of the same, and a diametrically reducedpipeconne'cted to the lower extremity of the cone or bell.
